Hi, I am not very sure . But I guess If we consider the servlet lifecycle the servlet is not supposed to get instantiated until requested for . So even if the transformation and compilation is done actual existence of unsed objects may not be the reason . So I am little bit skeptical about 16000 objects co-existing at the same time unused which is overloading the server.

As a perpetual Java beginner, my first reaction upon reading that number of JPS's above would be : let's enable Garbage Collector logging, and look at what it says. Maybe also, just to give us an idea, you could tell us how much memory that system has, and how much is given to use by Tomcat ? As far as I first understand such things, each of these JSP's gets compiled into a servlet, and the code of that servlet is held in memory for an extended period of time, even if unused at any particular moment. So this is 16000 servlets probably coexisting (un-)happily inside that JVM. No wonder.. Or am I totally off the mark here, Tomcat/Java experts ? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org This message contains information that may be privileged or confidential and is the property of the Capgemini Group.
